Export smart gaps state

[Michele Ferrante]

Hi, I’m currently setting up dk and I was wondering if there is a way to make another program aware of the smart gap state. The idea behind this need is a status bar setup that changes depending on the presence of gaps in the workspace.

‌

I tried looking at xdotool , wmctrl and similar solutions to try and guess if a workspace has only one window but the more I look the more I think that would be an extremely messy solution.

For what I’ve seen in the code the gap is silently set at 0 when only a window is available in the workspace, is there a way to make the change not silent?

Maybe it would be possible to use the rule and callback framework you put in place?

‌

Let me know your thoughts on this, and thank you for your work on this nice WM!

Sorry for the delay.

This seems like a good idea and should be easy enough to implement. I'll look into getting it done over the weekend. It will likely just be another field attached to workspaces in dkcmd status type=full num=1

Thanks for the suggestion and trying out the WM.

Add: status output for ws smart gap state, see #17

I've added the initial implementation, you'll still need a way to parse out the info but something like this will get you started

dkcmd status type=full num=1 | sed -n '/^workspaces:/,/^$/p'

Will give you something like this

workspaces: *1:1:tile 2:2:tile 3:3:tile 4:4:tile 5:5:tile 6:6:tile 7:7:tile 8:8:tile 9:9:tile 10:10:grid
        # number:name active_window nmaster nstack msplit ssplit gappx smartgap padl padr padt padb
        1:1 0x03800005 1 3 0.50 0.50 0 0 0 0 0 0
        2:2 0x02800002 1 3 0.50 0.50 0 1 0 0 0 0
        3:3 0x0040008b 1 3 0.50 0.50 0 0 0 0 0 0
        4:4 0x03a00005 1 3 0.50 0.50 0 1 0 0 0 0
        5:5 0x00000000 1 3 0.50 0.50 0 0 0 0 0 0
        6:6 0x00000000 1 3 0.50 0.50 0 0 0 0 0 0
        7:7 0x00000000 1 3 0.50 0.50 0 0 0 0 0 0
        8:8 0x00000000 1 3 0.50 0.50 0 0 0 0 0 0
        9:9 0x00000000 1 3 0.50 0.50 0 0 0 0 0 0
        10:10 0x00000000 1 3 0.50 0.50 50 0 200 200 100 100

And to just grab the smart gap state for each workspace in order you can do

dkcmd status type=full num=1 | sed -n '/^workspaces:/,/^$/p' | awk '{if ($8 ~ "[01]") print $8}'

0
1
0
1
0
0
0
0
0
0

0 smart gaps are not being used on that workspace, 1 smart gap is active (meaning no gaps and a single window)

Lemme know

Very nice, thanks!

Right now I'm out of town, but I'll try the change out as soon as I'm home and get back to you

[Nate Maia]

I think can be called done, if you run into any issues or have other ideas please let me know.

[Michele Ferrante]

Sorry for the unresponsiveness, I’m in the middle of the exam session at uni.

‌

That said I’m positive I can work with dkcmd status to get what I need, if I can get Polybar to cooperate.

Maybe if it works well enough with the bar we can think about making a callback for this situation instead of polling the status output, but we’ll cross that bridge when we come to it.

[Michele Ferrante]

If you’re curious about the effect:

‌

I managed to make Polybar comply, it was no easy task hahahah

‌

Thanks for the help anyway

[Nate Maia]

That looks really nice and well integrated.

I really appreciate your interest in the project and don't sweat any delays you might have, I'm not always great about timing either. I'd be willing to look into setting up some form of callback but honestly the status command is fairly fast and reasonably optimized. That being said I'm always down to improve things.
